hello, i came back to you.
I add the boot args: no results. My screen turns off when i launch my vm and no signal from any port.
i paste the last line in log of the vm
-device usb-tablet,id=input0,bus=usb.0,port=1 \
-audiodev '{"id":"audio1","driver":"none"}' \
-device vfio-pci,host=0000:41:00.0,id=hostdev0,bus=pci.3,multifunction=on,addr=0x0 \
-device vfio-pci,host=0000:41:00.1,id=hostdev1,bus=pci.3,addr=0x0.0x1 \
-sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \
-msg timestamp=on
char device redirected to /dev/pts/0 (label charserial0)
I modify the xml for passthrough like spaceinersone explain in its dedicated video.
for the web driver i put the last version on website.
I got no idea from now
Thanks
